Calculate the pipe cut length between two real fittings. Pipe Offset shows the cut piece, center-to-center travel, fitting deductions and joint gaps together, so you can follow the calculation from layout to cut. Built for pipefitters and steamfitters working with metric or imperial dimensions. Choose EN/DN, ASME/NPS or copper profiles, or enter a custom outside diameter. Fitting values carry source labels: standard, catalogue, theoretical or measured. When a table does not cover your fitting, enter its measured dimensions. OFFSETS AND FITTINGS Solve simple and rolling offsets. With the unlock, select fittings A and B independently at a shared angle, lay out parallel banks with cumulative marks, solve for a target run, or account for an obstacle and clearance. The drawing highlights the cut piece and shows the dimension chain. BRANCHES AND SEGMENTED ELBOWS Lay out branch connections with numbered ordinates for the branch cut and header opening. The unlock adds oblique and eccentric branches, segmented elbows and printable 1:1 PDF templates. Templates tile across A4 or Letter pages with a calibration ruler and overlap marks. Save offsets, branches and elbows as jobs and export PDF cut sheets. INCLUDED WITHOUT PURCHASE Simple and rolling offset calculations, axis dimensions and cut length using the region's default butt-weld elbow family, ASME LR or EN 3D, or your measured fitting values. Also includes one on-screen example of a centered branch at 90°. ONE-TIME UNLOCK One non-consumable purchase opens all included fitting catalogues, independent A/B fitting selection, parallel banks, target-run and obstacle tools, full branch tools, segmented elbows, saved jobs and PDF exports. No subscription. Restore Purchases is available in Settings. Works offline. No account or login. Saved jobs use local app storage.
